The 8 Best Uninterruptible Power Supplies

The APC BE600M1 is a practical UPS solution for homeowners and remote workers who depend on continuous internet and computer access. With 600VA capacity and 330W of usable power, it delivers 23 minutes of runtime at 100W load, which is enough time to safely shut down your system or ride out a brief power dip. The unit features 5 outlets with full battery and surge protection, plus 2 surge-only outlets for devices like printers or speakers that don't need battery backup.

What sets this model apart is its thoughtful desk design. The outlets are well-spaced to accommodate bulky power adapters, and the built-in 1.5A USB port keeps your phone charged during outages without consuming battery capacity from your computer. For homeowners dealing with frequent brownouts or brief interruptions, this combination of features provides real peace of mind without requiring a dedicated outlet strip elsewhere in your home.

Long-term value is enhanced by the user-replaceable battery cartridge (APC model APCRBC154), which means you can extend the unit's lifespan for years without buying a new UPS. The 3-year warranty and equipment protection plan add confidence that your connected devices are covered against power-related damage. This is an honest choice for protecting essential equipment on a budget.

Setup: Plug the UPS into a wall outlet and connect your computer, router, modem, and other critical devices to the battery-backed outlets (typically the top row). Connect less critical gear like printers to the surge-only outlets. Plug your phone charger into the USB port.

During an Outage: The UPS automatically switches to battery power, keeping your equipment running. You'll hear a beep and see indicator lights showing battery status. Use this time to save your work and properly shut down your computer. The USB port continues charging your phone throughout the outage.

Battery Replacement: When battery runtime drops noticeably (usually after 3-5 years), order the APC APCRBC154 replacement cartridge. Open the UPS case, disconnect the old battery, and plug in the new one. No tools or technical knowledge required. This extends your UPS lifespan without buying a new unit.

Load Priority: Plug your modem and router into battery-backed outlets first, then your computer. This ensures internet stays up longest, allowing you to upload work and stay connected during an outage.

Runtime Planning: At 100W load, you get 23 minutes. If you're running your computer plus router plus monitor, you're likely drawing 150-200W, which cuts runtime to 12-15 minutes. Plan your shutdown sequence accordingly.

Preventive Maintenance: Unplug the UPS and let it sit for 2-3 minutes monthly to keep the battery healthy. Avoid placing it in hot areas (above 77F) or near vents, as heat degrades battery lifespan faster.

Surge Protection Value: Even if you never experience an outage, the UPS protects against voltage spikes from everyday power fluctuations. This is especially valuable for expensive routers, NAS drives, and computer equipment.

Who Should Buy This: Remote workers, home office users, gamers with expensive setups, homeowners with frequent power dips, and anyone protecting a router or NAS drive. It's ideal if you live in an area with occasional outages or unstable power.

Who Might Need More: If you need runtime longer than 30 minutes, or if you're powering multiple computers and high-draw devices simultaneously, consider a higher-capacity model (1000VA or above). This unit is designed for single-computer setups and small networks.

Key Decision Points: Runtime is the main limitation. Calculate your typical power draw (computer + monitor + router) and confirm 23 minutes at 100W meets your needs. If you need the UPS mainly for safe shutdowns and internet continuity, this is plenty. If you need extended runtime for work continuation, you'll want more capacity.

Total Cost of Ownership: The 600VA price is low, but factor in a battery replacement (APCRBC154) every 3-5 years. This remains affordable compared to larger models, and the replaceable battery keeps costs down versus buying new each cycle.

The APC BX1500M delivers substantial backup power for home offices, entertainment centers, and smart home hubs. With 1500VA capacity and 900W output, it ranks among the highest-capacity UPS systems designed for residential use.

Built-in coaxial and Ethernet surge protection rounds out the defense against power anomalies.

The automatic voltage regulation (AVR) feature is a standout for homes experiencing frequent brownouts or voltage fluctuations. Rather than immediately draining the battery during minor power irregularities, AVR corrects low voltage and surges automatically, preserving runtime for actual blackouts. This approach also benefits active PFC power supplies found in modern gaming PCs and workstations. At a 100W load (typical for a computer setup), the unit provides approximately 68 minutes of backup time, which is reasonable for gracefully shutting down systems or riding out brief outages.

Long-term value is enhanced by the user-replaceable battery design and ENERGY STAR certification. Unlike many UPS units that require professional service when the battery ages, the BX1500M lets homeowners swap the battery independently, avoiding downtime and service fees. The 3-year warranty and $75,000 equipment protection policy reflect APC's confidence in the unit's durability and provide meaningful coverage for expensive connected devices. The LCD display keeps you informed with real-time monitoring of battery status and runtime estimates.

Initial Setup: Unpack the unit and place it on a flat, well-ventilated surface near your equipment. Plug the UPS into a wall outlet and allow the battery to fully charge before connecting your devices (typically 4-8 hours for first charge).

Connecting Devices: Plug essential devices (computer, modem, router, external drives) into the five battery backup outlets (usually marked). Connect non-critical devices like monitors and printers to the five surge-only outlets. The unit will automatically switch to battery power during an outage.

Monitoring Status: Check the LCD display regularly to see battery charge level and current load percentage. During normal operation, the display shows input voltage and load capacity. When an outage occurs, it displays estimated runtime remaining so you can prioritize shutdowns.

Battery Maintenance: Keep the unit plugged in during normal operation so the battery stays charged. Most UPS batteries last 3-5 years; when runtime drops noticeably, order the replacement battery (APCRBC124) and follow the simple swap procedure in your manual.

Is This the Right UPS for You? The BX1500M suits homeowners with home offices, small server setups, entertainment systems, or smart home hubs.

It's also ideal for protecting valuable electronics like gaming PCs, NAS systems, and home theater equipment from power surges and voltage swings.

Capacity Considerations: With 900W output, this unit can support multiple devices simultaneously, but not a full household. A typical computer setup (tower + monitor + peripherals) draws 200-400W, leaving headroom for routers, modems, and other smart devices. If you need to protect high-power devices like refrigerators or HVAC systems, you'll need a larger, commercial-grade UPS.

Runtime Expectations: The 68-minute runtime at 100W is sufficient for most home office scenarios: shutting down a computer gracefully, running a router through a brief outage, or keeping security cameras and smart home hubs online. For extended blackouts, prioritize which devices stay powered and which you'll shut down first.

Warranty and Support: The 3-year warranty and $75,000 equipment protection provide strong coverage. Keep your receipt and register the product with APC to activate the full warranty benefits. The user-replaceable battery is a major advantage for long-term ownership, as it eliminates expensive service calls.

Optimize Your Outlet Layout: Reserve the five battery backup outlets for your most critical devices: computer, modem, router, and external drives. Plug lower-priority items like desk lamps, phone chargers, and monitors into the surge-only outlets. This maximizes runtime for devices that truly need uninterrupted power.

Leverage AVR for Voltage Stability: The automatic voltage regulation corrects minor power fluctuations without draining your battery. This is especially valuable in areas prone to brownouts or unstable grid voltage. Your devices stay protected, and your battery lasts longer for actual blackouts.

Plan Your Load: Calculate the wattage of devices you'll run simultaneously during an outage. A typical setup (computer tower 300W + router 20W + modem 15W + external drive 10W) totals about 345W, leaving you well under the 900W limit and providing extended runtime.

Test Your Setup: Once installed, periodically disconnect the unit from the wall outlet for 10-15 seconds to confirm everything switches to battery power smoothly. This ensures your devices are truly protected and gives you confidence in the system before a real outage occurs.

Battery Replacement Timing: Most users replace the battery every 3-5 years depending on usage patterns and climate. Mark your calendar when you first install the unit so you're not caught off guard. Keeping a spare battery on hand eliminates downtime if replacement becomes urgent.

The APC BR1500MS2 stands out as a serious UPS option for homeowners and professionals who depend on their computer systems staying online. Its pure sine wave output is a critical advantage over budget UPS models that use simulated sine waves, which can cause damage to modern electronics like NAS drives, gaming PCs, and high-end monitors over time. With 1500VA/900W of capacity and up to 73 minutes of runtime at minimal load, this unit gives you enough time to safely shut down your system, save active work, or ride out brief power interruptions entirely.

Is This UPS Right for You? The BR1500MS2 works best for home office setups, gaming PCs, small server rooms, or creative workstations where you have multiple devices that need protection. If you're running a single laptop or light computing load, a smaller 650VA or 1000VA unit may suffice. However, if you have a desktop PC, monitor, NAS drive, router, and peripherals all drawing power, this 1500VA capacity provides comfortable headroom.

Pure Sine Wave vs. Simulated Wave Don't overlook the pure sine wave specification. Modern power supplies with Active Power Factor Correction (PFC) and sensitive devices like NAS drives, printers, and audio equipment can be damaged by the simulated sine waves produced by cheaper UPS units. Pure sine wave output ensures clean, stable power that matches your wall outlet quality.

Runtime Expectations At full 900W load, runtime will be significantly shorter than the 73-minute figure (which applies at 100W). Plan on 15-25 minutes at typical office load (300-500W). This is enough to safely save your work and shut down gracefully, not to power your entire setup for hours. If you need extended runtime, consider pairing this with a larger battery pack or stepping up to a higher capacity model.

Maintenance and Battery Replacement The user-replaceable battery is a major advantage. When battery capacity degrades after 3-5 years, you can swap in a new APCRBC163 battery for around $80-120 instead of replacing the entire unit. Keep the UPS in a cool, dry location and avoid constant high-load operation to extend battery lifespan.

Outlet Strategy Assign your 6 battery-backed outlets strategically: PC tower, monitor, router, and NAS get priority. Use the 4 surge-only outlets for printers, speakers, or desk lamps that don't need battery backup. This maximizes your runtime by avoiding unnecessary drain from non-critical devices.

Voltage Regulation Benefit The AVR feature is your silent protector. In areas with chronic power quality issues (voltage sags or spikes), leave this unit powered on 24/7 even when your PC is off. It will silently regulate incoming power and extend the lifespan of all connected electronics, including your router and NAS.

Monitor the LCD Display Check the load percentage displayed on the LCD regularly. If you're consistently running above 80% of capacity during normal operation, you're pushing the limits and should consider upgrading. This helps you plan for future expansion before you hit the ceiling.

Test Your Setup Once installed, manually trigger a brief battery test by flipping the power switch or unplugging the unit for 10 seconds to confirm all your critical devices are properly connected and functioning on battery power. Don't wait for a real outage to discover a problem.
